Background: In Parkinson's disease (PD), gait disorders lead to increased risk of falls and patients' reduced participation and independence. Several observations suggest that a single session of focal muscle vibration (fMV) applied to trunk or lower limb muscles during gait may improve several gait variables in patients with PD. The possible long-term beneficial effects of repetitive sessions of fMV (r-fMV) on gait of patients with PD have been investigated.
Methods: A randomized, controlled trial study has been conducted in an outpatient rehabilitation department. Twenty patients with PD diagnosis have been randomized in two groups: "real" or "sham" r-fMV application to quadriceps and paraspinal muscles in patients with PD. Gait was evaluated with objective gait analysis, and a number of variables, including velocity, step length, stride length, percentage of stance, double support duration, cadence, swing velocity, and step width, have been measured. Gait analysis was performed before and 24 hours and 1 and 3 weeks after r-fMV.
Results: After real, but not sham, r-fMV, patients with PD had significant gait improvement as a result of increased walking velocity and stride length. The r-fMV-induced beneficial after effects lasted at least 1 week after the end of stimulation.
Conclusions: Data emerging from our pilot randomized, controlled trial study suggest that r-fMV may improve gait disorders in patients with PD. r-fMV might be a feasible, safe approach for possibly improving gait disorders in patients with PD and might enhance the impact of specific rehabilitation programs in PD.

Introduction: Intrusive memories occur frequently after potentially traumatic events and form a core symptom of posttraumatic stress disorder (PTSD) if they persist. The translational approach of visuospatial interventions tries to target those intrusive memories in order to reduce their frequency predominantly using an intervention including as one component the computer game Despite promising results, the application of has critical drawbacks, e.g.

Purpose: Oral corticosteroids (OCS) are recommended for the treatment of exacerbations in people with COPD; however, high cumulative lifetime doses (≥1000mg prednisolone-equivalent) are associated with adverse health effects. This issue is well defined in asthma but is less well understood in COPD. The aim of this study was to examine cumulative OCS dispensed to people with COPD over 12 months.

Background: In a recent randomized trial, six months of financial incentives contingent for recent alcohol abstinence led to lower levels of hazardous drinking, while incentives for recent isoniazid (INH) ingestion had no impact on INH adherence, during TB preventive therapy among persons with HIV (PWH). Whether the short-term incentives influence long-term alcohol use and HIV viral suppression post-intervention is unknown.
Methods: We analyzed twelve-month HIV viral suppression and alcohol use in the Drinkers' Intervention to Prevent Tuberculosis study, a randomized controlled trial among PWH with latent TB and unhealthy alcohol use in south-western Uganda.

Background: Brain stimulation therapy (BST) has significant potential in treating psychiatric, movement, and cognitive disorders. Given the high prevalence of comorbidities among these disorders, we conducted an umbrella review to comprehensively assess the efficacy of BSTs in treating the core symptoms across these three categories of disorders.
Methods: We systematically searched for meta-analyses and network meta-analyses of randomized controlled trials with sham controls up to September 25, 2024, from databases including PubMed, PsycINFO, Embase, and the Cochrane Library.
